1. INTRODUCTION

1.1. General description of the Toktogul HPP and context

1. The Toktogul Dam is a concrete gravity dam, with a height of 215 m, and is equipped

with a large hydropower plant of 1200 MW capacity. The Toktogul hydropower plant

(HPP) provides 40% of the average Kyrgyz Republic electricity output. The dam’s

construction began in 1960 and the hydropower plant was put into services in 1975

(Picture 1).

2. The Toktogul HPP plays a major role on Kyrgyz Republic electrical grid and on the

Central Asian power system, providing energy and frequency regulator services. It is

equipped with 4 vertical Francis units of 300 MW each, and has never been significantly

rehabilitated since its commissioning.

3. The Kyrgyz Republic has received a funding from the Asian Development Bank and the

Eurasian Development Bank for the Phase 2 of Toktogul HPP Rehabilitation Project.

The executing agency of this project is the Open Joint-Stock Company Electric Power

Plants (EPP).

4. Rehabilitation studies and rehabilitation works are divided into 3 phases. During the

reporting period, no construction activities have been started yet. This report is the fourth

Bi-annual EMR for Rehabilitation of Toktogul HPP Phase 2 Project.

1.2. Objective of the rehabilitation works

5. The general objective of the rehabilitation works is to improve the technical and

operational performances of Toktogul HPP. Considering the strategic importance of

Toktogul HPP for the stability of the national and regional grid, there are two main

objectives that can be identified:

• To recover a proper reliability and availability of the plant,

• To increase the capacity of the power plant.

1.2.1. Original scope of work for Phase 2

6. As originally planned, the Phase 2 required completely rehabilitating/replacing the Units

n°2 and n°4 with their auxiliary systems and was divided into the two following lots:

• Package 1 of Phase 2 concerns the Rehabilitation of Gates & Hydraulic

Steel Structures (International competitive bidding, single stage, one

envelope):

• Package 2 of Phase 2 concerns the rehabilitation of the two units 2 and 4

(International competitive bidding, two stages with pre-qualification, and two

envelopes) and their auxiliary systems.

1.2.2. Modified scope of work for Phase 2

7. Decision was taken to group in a single phase the rehabilitation of 4 units and to replace

the existing units by completely new units with the exception of the main embedded

parts.

8. Additionally, in order to speed up the bidding process, it was decided to cancel the pre-

qualification stage and to replace it by a road show that took place in September 2015.

9. The content of the different phases becomes as follow:

• In addition to the original forecast, the scope of the Phase 1 will also cover

the replacement of the main transformer for the 4 units.

• The Phase 2 will consist in completely replacing the 4 units with their

auxiliary systems and will be divided into the 2 following lots:

o Package 1 of Phase 2 will concern the Rehabilitation of Gates &

Hydraulic Steel Structures related to the 4 units as well as the

rehabilitation of spillway and bottom water outlet gates.

o Package 2 of Phase 2 will concern the replacement of the 4 units and

their auxiliary systems.

OF THE STATE ENVIRONMENTAL EXPERT REVIEW

to the Report “Initial Environmental Examination (IEE), Rehabilitation of Toktogul HPP, Phase 2” of the Energetic Sector Rehabilitation Project ADB-ТА-8434 (KGZ)

The Report “Initial Environmental Examination (IEE), Rehabilitation of Toktogul HPP, Phase 2” of the Energetic Sector Rehabilitation Project AБР-ТА-8434 (KGZ) developed by Fichtner in 2014 on request of ADB and “Electric Power Plants” OJSC was submitted to the State Agency on Environment Protection and Forestry under the Government of the Kyrgyz Republic to carry out state environmental expert review.

The Initial Environmental Examination (IEE) of the Rehabilitation of Toktogul HPP, Phase 2” of the Power Sector Rehabilitation Project ADB-ТА-8434 (KGZ) consists of the following major sections:

1. Summary 2. Political, Legal and Administrative Frameworks 3. Description of the Project 4. Description of Environment 5. Expected environmental impacts and mitigation measures 6. Analysis of alternatives 7. Disclosure of information and consultation 8. Grievance Redress Mechanism 9. Environment Management Plan 10. Conclusion and Recommendations 11. Annexes

Implementation schedule: The construction shall start in second half of 2016 and last until 2020/2021.

Description of the Project and possible impacts:

The following activities will be carried out in the course of works at Toktogul HPP:

- replacement/rehabilitation of two turbines: - replacement/rehabilitation and upgrading of two generators;

16

- replacement of two main transformers associated with two turbines / generators; - replacement of unit control systems for two units; - replacement of unit protection systems, including relevant transformer, loop and fencing

for two units; - replacement of a unit of electrical and mechanical auxiliary systems (MV and LV

switchgears, cooling system, drainage and water-pumping systems, etc.) for two units (for units);

- rehabilitation of hydraulic steel structures and hydromechanical equipment at the outlet and downstream;

- rehabilitation of hydraulic steel structures and hydromechanical equipment (pressure conduits, bottom outlets, taps, etc.).

Toktogul HPP Rehabilitation Project is a unique project and a vital link for regulation of voltage frequency of 500 kV transmission systems, which connects the Central Asian countries. Capacity of HPP was well built, but many components should be currently replaced to maintain generating integrity. Consequently, there is no other realistic alternative but one that suggests consistent replacement of worn-out equipment and relevant maintenance of engineering structures and installed equipment.

According to Examination, the following possible impacts on the environment may be associated with rehabilitation activities listed above:

- possible power outage during construction; - disposal of old oil (about 180 tons that do not contain PCBs according to conducted

analysis); - issues of occupational health and safety compliance during construction; - increase in truck movements through settlements during construction period;

transportation of heavy equipment, building materials and debris; - disposal of iron / steel (almost 4000 tons) and other wastes; - construction debris generated because of construction work, and some domestic waste

generated because of daily living activities of workers.

As a part of IEE it is provided for to identify proposed Project impacts on the environment and to plan appropriate preventive actions and mitigation measures to prevent, minimize or eliminate expected adverse effects. Potential environmental impact of the Project will be of local and temporary nature. To mitigate the impact on the environment, there is developed Environmental Management Plan (EMP), which provides for collection, storage and sale of scrap metal and re-use the oil from equipment to be replaced etc..

Public consultations and public meetings were conducted in Karakul Town of Jalal-Abad oblast when the Report was being prepared. Participants of those consultations and meetings mainly considered waste related matters and methods of coping with them. Eventually everybody came to conclusion that rehabilitation measures provided by the ADB Project on rehabilitation of Toktogul HPP were necessary. Having considered submitted materials, the State Agency on Environment Protection and Forestry under the Government of the Kyrgyz Republic issues positive opinion on the State Environmental Expert Review to the Report “Initial Environmental Examination (IEE), Rehabilitation of Toktogul HPP, Phase 2” of the Energetic Sector Rehabilitation Project ADB-ТА-8434 (KGZ). At the same time it is required that:

- “Electric Power Plants” OJSC must ensure that reports on environment protection are timely submitted and statutory payments for environmental pollution are timely paid to the Jalal-Abad Territorial Department of SAEPF during implementation of the Project.

- Jalal-Abad Territorial Department of SAEPF must be notified before beginning of work.

If the conclusion of the State Environmental Expert Review is not complied with and if works are not executed according to design decisions, the conclusion shall automatically become void.
